What has happened to this code

Every change the publisher made, from 2010 to now. Entries marked draft are from the pre-implementation releases: ICD-10 took effect on 1 October 2015, so nothing before FY2016 was ever valid on a claim.

FY2010 Added to the draft code set draft Subcutaneous panniculitis-like T-cell lymphoma
FY2025 Stopped being billable
